| .SH NAME |
| curl_free - reclaim memory that has been obtained through a libcurl call |
| .SH SYNOPSIS |
| .nf |
| #include <curl/curl.h> |
| |
| void curl_free(void *ptr); |
| .fi |
| .SH DESCRIPTION |
| curl_free reclaims memory that has been obtained through a libcurl call. Use |
| \fIcurl_free(3)\fP instead of free() to avoid anomalies that can result from |
| differences in memory management between your application and libcurl. |
| |
| Passing in a NULL pointer in \fIptr\fP makes this function return immediately |
| with no action. |
| .SH EXAMPLE |
| .nf |
| int main(void) |
| { |
| char *width = curl_getenv("COLUMNS"); |
| if(width) { |
| /* it was set! */ |
| curl_free(width); |
| } |
| } |
| .fi |
